Add shell pipe support for "play kube"

[ADIX7]

Closes #8996

Similar to cat pod.json | kubectl apply -f - this commit adds support
for input from shell pipe (ex cat pod.json | podman play kube -).
To use input form pipe one may use '-' as file name, the same way as
kubectl apply -f -

Needs to be unset as a WIP before merging

[ADIX7]

Your welcome! The documentation and tests are still needed. I guess they should be done before merging, right?

Yes, please

This does not work with podman-remote. You have to make a similar change in pkg/domain/infra/tunnel/play.go

What should be the new usage syntax? kube [options] KUBEFILE|- ? Or it should remain kube [options] KUBEFILE ?

[rhatdan]

I think we can just leave this as kube [options] KUBEFILE and then explain in the decription that "-" can be used as a kubefile name.

I see #9420 went in, closing this one.
